In my experience the Android-formatted SD card is not readable as standard partitions.|
A Windows system (and possibly Linux too) just can't make sense of the contents.
So attempting to check the card for content on the system that flashed it is pointless.
The only Windows softwares I know of which can handle the card contents are the "PhoenixCard" program that writes the card, and the "Win32 Disk Imager" which can backup and later restore the contents of such an Android card. There may be others, but none that I know of.
